Important features that affect the number of visitors
Time and Date are the most important variables. 
Effect of hours on visitors count
- We can see that there are many customers at night from 7pm until 12pm, but the highest number of visitors were at 22pm and 23pm.
The effect of the day on visitors count
- weekends have the highest number of visitors.

Weekends have higher number of visitors, and after 11 pm there are more visitors.
Daily Trend
It is the same for the profit, weekends have higher number of visitors, and after 11 pm there are more visitors.
Seasonality
- It is a repeating pattern within a year. We can not see that in our data because we don’t have a record for a whole year.
There is no Seasonality in my data.
Conclusion
To increase the number of visitors and thus profits, I suggest focusing on weekends and night hours as they tend to increase the number of people. Also, removing unprofitable products and increasing the number of profitable products may help.
